Abstract
Quality assessment in existing road pavement was used to decide the right action for road preservation. In Indonesia, the quality was measured by functional using International Roughness Index (IRI) and visually using Pavement condition Index (PCI) to evaluate driver convenience. However road quality structurally can be assessed by measured the deflection and elasticity modulus by using light weight deflectometer (LWD) test. Four (4) segments of national arterial road in Kupang City, East Nusa Tenggara Province data were collected using Light weight defletometer test to find the deflection and elasticity modulus. The result of this test then compared to the result of International roughness index (IRI) test and Pavement condition index (PCI) on the same segments. The statistic result of mean, coefficient of varian and coefficient of correlation were obtained in this research
